Causes of skin cancer
Similar to many other types of cancer, skin cancer is not only caused by one etiologic factor. In most cases, the etiology combines a genetic predisposition with a type of skin and a series of environmental factors that usually include sun exposure or radiation. However, as you will see in this list of causes, even patients without excessive sun exposure may develop skin causes for many other causes.
We can summarize the typical risk factors and causes of skin cancer as follows:
1) Sunlight exposure:
It is listed as the first cause because it is the most frequent association with the majority of types of skin cancer. Exposure to radiation has a cumulative effect on skin cancer, and it is imperative to prevent this cause of skin cancer during childhood because it has a latency period of up to 50 years to develop. Ultraviolet rays are known to change the chemical bonds and structure of nucleic acids and promote DNA mutations. If the mutations happen to activate oncogenes or inactivate tumor suppressor genes, skin cancer ensues, and the effects may take some time to show up depending on the type of cancer.
